I've flown into and out of grass runways as a passenger. I think the
sensation depends very much on the quality of the runway. One runway
we flew off of was quite nice, hard packed and pretty smooth. One
runway we landed at was, well, hard to call a runway. It was an area
cleared out of the jungle and I suspect they left in the stumps. It
sounded like the aircraft was shreding itself when we touched down.
But we got in and out of there ok. Apparently Helio Super Couriers
are tough birds:

Yeah, I've been up in that Cat too :-) (but I was only 4 so I don't
remember much.) I also do remember seeing it land on the lake a few
times, and then taxi out up the concrete ramp. Must have been
impressive to get burned in the old neurons like that. :-)
Regards,
Curt.
